of farm-yard manure.
The complete commercial fertilizers-that

nitrogen. phosphoric acid and potash-con-
tain ON an average about three lbs. of nit
rorcn. 10 or IL lbs. of soluble, reverted
and insolube phosphoric acid, and four lbs.
of potash to each hundred pounds of the
fertilizer. Taking the above statement for
the value of the manure, long ton con
tuns about three times as much nitrogen,
twice as much potash, and not quite as
much phusphoric acid as a hundred pounds
of fertilizer. The 100 lbs. OF artificial fer
tilizer, composed of the parts given above,

In the above estimate We have called the

IN the manure we have estimated at the
price made at the experiment station for
nitrogen in fine medium hone, and the
phnsphoric acid at the price of the msolu-
hle acid in medium bone. According to

The large quantity of phosphoric acid il
this sample suggests possible error in tn
figures. or it NAV be accounted for by tn
sample having had for long time tn
drainage of urine in the yard. Taking tn
figures as they stand. it would require 1
hounds of fertilizer to Ice equal in value t
